Refactor logging mechanism for kuksa-client

[erikbosch]

Keep print only for things that can be printed in CLI Adapt config to method used by other providers.
Logging framework from kuksa-can-provider reused here.
Fixes #25

When merged and a new kuksa-client pypi package has been released we can (if we like) update clients to avoid code duplication. An example is given in eclipse-kuksa/kuksa-can-provider#22

Example new behavior

This is an improvement related to #27 - give an error if we by some reason cannot dump the response as json.

[SebastianSchildt]

Code looks "reasonable" to me, and did a couple of maunal tests with the client

Appreciate getting rid of the remaining "prints"

Well there are still "prints", like the fancy logo and output of results, but that is sort of expected if you have a CLI.
